2007 Chrysler-Jeep 300 3.0L Diesel · SL07 XCU

The 2.987 cc diesel engine typically delivers around 35‑38 mpg (≈7.5 L/100 km), which at an average annual mileage of 12,000 mi translates to roughly £1,200‑£1,500 in fuel costs. Road tax for a diesel over 2.5 L is higher, currently about £150 per year, and insurance for a 2007 300 diesel falls in group 15‑18, costing approximately £600‑£800 per year.

Routine maintenance – including oil and filter changes, fuel filter replacement and occasional brake service – is expected to add £300‑£400 per year. Factoring in these items, the estimated total annual running cost is £800‑£1,200.

Inspect the oil leak source (advisory 8.4.1) and ensure it is minor; check the engine oil level and look for fresh leaks after a short drive. Examine tyre tread depth and side‑wall condition, especially the near‑side tyres that have repeatedly been noted as worn close to the legal limit.

Pay close attention to the braking system – the MOT history shows corroded front brake pipes (advisory 1.1.11(c) and 3.6.B.2c) and previous failures of brake efficiency and parking brake. Verify that brake pads, discs and the parking brake mechanism are in good condition and that there is no excessive play in the steering rack or suspension components such as bushes, ball joints and shock absorbers, which have failed in earlier tests.

Finally, check the underbody for rust, especially around the under‑trays and chassis rails, confirm all wheel nuts are present and securely tightened, and test the washer fluid system to ensure it supplies adequate liquid.
